Patent CA-2190268-A1 (CA)
Inventor: BOEHM WOLFGANG
IPC: A61K35/14
Filed: 1995-05-15
Abstract: The invention provides a method for producing a sterile and pyrogen-free column coupled to protein for use in removing a predetermined substance from the blood of a human subject. The method abrogates sterilization of the finished protein-containing product by providing sterile and pyrogen-free raw materials at each production step. The method provides a pathogen-free, purified solution of protein which binds to a predetermined substance in human blood such as LDL or immunoglobulin.  Typically, the protein is anti-human LDL immunoglobulin or anti-human Ig immunoglobulin.  The method also provides a sterile and pyrogen-free column matrix material such as an agarose which is chemically activated, either using CNBr and triethylamine or using 1,1'-carbonyldiimidazole. The sterile and pyrogen-free, activated matrix material and the pathogen-free, purified protein solution are combined under aseptic conditions to effect the coupling of the protein to the matrix material, and the protein-coupled matrix material is filled under aseptic conditions into a sterile and pyrogen-free housing to produce a sterile and pyrogen-free column.

Title: Memory management in a partially garbage-collected programming system
Inventor: THOMSON BRIAN WARD
IPC: G06F12/02
Filed: 1997-12-24
Abstract: Memory management to support calls between objects in language environments support automatic garbage collection and language environments requiring explicit control of object destruction is provided. Reference counting is used to automatically control the lifetime of objects requiring explicit destruction and that are to be accessible across the language boundary. A data structure is maintained in a runtime component for each object that is accessed over a language boundary. The reference count for each non-garbage collected object is incremented by the runtime in accordance with the number of cross-language references held to it. When the count reaches zero through decrements as the references are returned and destroyed, the non-garbage collected object can be safely and automatically destroyed. The runtime creates a strong reference to any garbage collected object accessed by a cross-language call. The reference is visible to the garbage collector, and prevents the object being collected while the reference is in existence.

Title: Npf roller
Inventor: FUKS VLADIMIR
IPC: B65G39/02
Filed: 1998-08-19
Abstract: Roller is very common part for any kind of the materials handling equipment.  Some of the handling equipment, like Roller Conveyor, using the surface of the rollers to transport big lumps or boxes or other lumpy products. Other handling equipment, like Belt Conveyors, using the rollers as a supporting element for the moving belt. Most of the rollers have a shaft and a rolling shell supported by bearings.  Under the load of the handled material, the roller's shaft and the shell are deflected. The effect of the deflection is a function of the load and rigidity. When the load is higher the deflection getting bigger. The shaft of the roller is much more flexible than the shell and then the deflection of the shaft (under the same load) is higher than the shell. With increasing of the load, growing the difference of the deflection between the shaft and the shell.      Effect of the non-equal deflection creates few mechanical problems. One of the problems is, that the non-equal deflection (of the shaft and the shell) creates the angular misalignment of the bearings. The durability of the hearing is in inverse proportion to the angular misalignment. The bearing can function reasonably up to certain level of the angular misalignment. This limitation is accounted during the design of the roller. The second problem is, that during rotation of the shell (under the load) the unequal deflection (of the shaft and the shell) causes the pumping effect at the sealing area of the bearings. This effect is in direct proportion to the load on the roller. The pumping effect creates movement of the air through the labyrinth of the seals. Because of the existing pumping effect, all the rollers which are used in the dusty environment, required much more sophisticated seals in order to reduce the contamination of the bearing. The conventional design of the rollers, reduces but can not eliminate completely the pumping effect. The invention (Fig. 5) used to overcome the above mentioned mechanical problems.
